Thank you for purchasing the Wireless Radio Link DC
Powered Smoke Alarm. Wireless Radio Link Technology is
the easy, cost-effective way to provide your family with
whole-home safety. All Wireless Radio Link Alarms
communicate with each other without wires or connectors.
When one Alarm sounds, they all sound. This provides your
family with an earlier warning of potential danger, and gives
you more time to react.
The communication distance (range) between any two
Wireless Radio Link Alarms is typically 100 feet (30 meters)
inside of a home. Some features of a home, such as the
number of floors, number/size of rooms, furniture and types
of building materials used may reduce the range of the
Alarms. Examples include: suspended ceilings, ductwork,
large metallic appliances (refrigerators) and metal studs. A
feature of Wireless Radio Link Alarms is that they operate
as a mesh network. All Alarms will repeat any alarm signal
that is received to all other Wireless Radio Link Alarms.
Interference from structural conditions can be overcome by
adding additional Alarms to route the wireless signal around
obstructions.

IMPORTANT!
• The range and proper operation of any wireless device
will vary depending on its surroundings. It is very important
that each Alarm is tested individually before and after
installation to make sure that all Alarms respond properly.
• The Wireless Radio Link Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested
after changes to your home such as remodeling, moving
furniture, and with metal doors opened and closed.
Your Wireless Radio Link Smoke Alarm will automatically
communicate potential fires with all other Wireless Radio
Link Smoke Alarms.

1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the
bedrooms. Try to protect the exit path as the bedrooms are
usually farthest from the exit. If more than one sleeping
area exists, locate additional alarms in each sleeping area.
• Locate additional alarms to protect any stairway as
stairways act like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical
appliances are operated(i.e. portable heaters or
humidifiers).
• Locate an alarm in every room where someone sleeps
with the door closed. The closed door may prevent the
alarm from waking the sleeper.
• Smoke, heat, and combustion products rise to the ceiling
and spread horizontally. Mounting the smoke alarm on the
ceiling in the center of the room places it closest to all
points in the room. Ceiling mounting is preferred in ordinary
residential construction.
• For mobile home installation, select locations carefully to
avoid thermal barriers that may form at the ceiling. For
more details, see MOBILE HOME INSTALLATION below.
• When mounting an alarm on the ceiling, locate it at a
minimum of 4” (10 cm) from the side wall (see Figure 1).
• When mounting the alarm on the wall, it is best to use an
inside wall with the top edge of the alarm at a minimum of
4” (10 cm) and a maximum of 12” (30.5 cm) below the
ceiling, (see Figure 1).
• Put smoke alarms at both ends of a bedroom hallway or
large room if the hallway or room is more than 30 feet (9.1
m) long.
• Install Smoke Alarms on sloped, peaked or cathedral
ceilings at or within 3ft (0.9m) of the highest point
(measured horizontally). NFPA 72 states: “Smoke alarms
in rooms with ceiling slopes greater than 1 foot in 8 feet
(.3m in 2.4 m) horizontally shall be located on the high side
of the room.” NFPA 72 states: “A row of detectors shall be
spaced and located within 3 ft (0.9m) of the peak of the
ceiling measured horizontally” (see Figure 3).

MOBILE HOME INSTALLATION
Modern mobile homes have been designed and built to be
energy efficient. Install smoke alarms as recommended
above, refer to RECOMMENDED LOCATIONS and Figure
1. In older mobile homes that are not well insulated
compared to present standards, extreme heat or cold can
be transferred from the outside to the inside through poorly
insulated walls and roof. This may create a thermal barrier
that can prevent the smoke from reaching an alarm
mounted on the ceiling. In such units, install the smoke
alarm on an inside wall with the top edge of the alarm at a
minimum of 4” (10 cm) and a maximum of 12” (30.5 cm)
below the ceiling (see Figure 1). If you are not sure about
the insulation in your mobile home, or if you notice that the
outer walls and ceiling are either hot or cold, install the
alarm on an inside wall. For minimum protection, install at
least one alarm close to the bedrooms. For additional
protection, see SINGLE FLOOR PLAN in Figure 2.

sound 3 beeps, pause, 3 beeps.)
WARNING: TEST YOUR SMOKE ALARM OPERATION
AFTER R.V. OR MOBILE HOME VEHICLE HAS BEEN IN
STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE
A WEEK DURING USE.
8. Attach the Smoke Alarm to the mounting bracket. Line
up the guides on the alarm’s base with the guides on the
mounting bracket. When guides are lined up, turn the
base clockwise (right) until it snaps into place.
9. Test the Smoke Alarm. See “Weekly Testing.”
2. LOCATIONS TO AVOID FOR ALARMS
In general, alarms should not be located:
• In the garage. Products of combustion are present when
you start your automobile.
• Less than 4” (10cm) from the peak of an “A” frame type
ceiling.
• In an area where the temperature may fall below 40ºF or
rise above 100ºF.
• In dusty areas. Dust particles may cause nuisance
alarms or failure to alarm.
• In very humid areas or near a bathroom. Moisture or
steam can cause nuisance alarms.
• In insect-infested areas.
• Smoke alarms should not be installed within 3 ft (0.9m)
of the following: The door to a kitchen, the door to a
bathroom containing a tub or shower, forced air supply
ducts used for heating or cooling, ceiling paddle or whole
house ventilating fans, or other high air flow areas.
• Kitchens. Normal cooking may cause nuisance alarms. If
a kitchen alarm is desired, it should have an alarm silence
feature or be a photoelectric type.
• Near fluorescent lights, amateur radios, electrical
equipment or other devices known to transmit in the RF
band. Electronic “noise” may cause nuisance alarms.
• Near large metal surfaces and bundles of wire.

3. INSTALLATION INSTRUCTIONS
1. Hold base firmly and twist the mounting bracket
counterclockwise to separate it from the base.
2. Hold the mounting bracket against the ceiling (or wall)
so the vertical mounting slot is aligned in the 12 o’clock
position and trace around the inside of the mounting
slots (vertical and horizontal mounting).
3. Put the unit where it won’t get covered with dust when
you drill the mounting holes.
4. Using a 3/16” (5 mm) drill bit, drill a hole through the
center of the oval outlines you traced.
5. Insert the plastic screw anchors (in the plastic bag with
screws) into the holes. Tap the screw anchors gently
with a hammer, if necessary, until they are flush with
the ceiling or wall. (see Figure 4).
6. Attach the mounting bracket to the ceiling or wall.
7. Install the battery (included). Open the battery drawer.
Match the terminals on the end of the battery with the
terminals on the unit. Match “+” to “+” and “-” to “-.”
Push the battery in until it snaps in securely and cannot
be shaken loose. If the battery is not snapped in
completely, the unit cannot receive battery power. (see
Figure 5)

4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once a fresh
battery is installed and testing is complete. When products
of combustion are sensed, the unit sounds a loud 85db
pulsating alarm until the air is cleared.
FLASHING LED LIGHT: This smoke alarm is equipped with
a flashing red indicator light. The light will flash every 30 40 seconds to indicate that the smoke alarm is receiving
power
SMOKE SENSING CHAMBER OPERATION: This alarm
will “chirp” if any of the components in the smoke sensing
chamber fail. This chirp will occur between the flashes of
the red LED indicator light. (If the chirp occurs at the same
time as the red LED flash, see Section 6 for low battery
information.)
SELF TESTING: Test by pushing the test button on the
cover. This unit’s red LED will flashes and the unit would
“chirp” three times, if the electronic circuitry, horn, and
battery are working. If no alarm sounds, the unit has
defective batteries or other failure. You can also test the
NOTE: After you install the battery, the power
indicator light may flash. (If the unit alarms, the
light will blink rapidly, and the horn will repeatedly

alarm by blowing smoke into it.
have sensing limitations. Ionization type alarms offer a
broad range of fire sensing capabilities but are better at
detecting fast flaming fires than slow smoldering fires.
Photoelectric alarms sense smoldering fires better than
flaming fires. Home fires develop in different ways and are
often unpredictable.
Neither type of alarm (photoelectric or ionization) is always
best, and a given alarm may not always provide warning of
a fire.
• A battery powered alarm must have a battery of the
specified type, in good condition and installed properly.
• A.C. powered alarms will not operate if the A.C. power
has been cut off, such as by an electrical fire or an open
fuse.
• Smoke alarms must be tested regularly to make sure the
batteries and the alarm circuits are in good operating
condition.
• Smoke alarms cannot provide an alarm if smoke does not
reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, walls, on roofs, on the other side
of a closed door or on a different floor.
• If the alarm is located outside the bedroom or on a
different floor, it may not wake up a sound sleeper.
• The use of alcohol or drugs may also impair one’s ability
to hear the smoke alarm. For maximum protection, a smoke
alarm should be installed in each sleeping area on every
level of a home.
• Although smoke alarms can help save lives by providing
an early warning of a fire, they are not a substitute for an
insurance policy. Home owners and renters should have
adequate insurance to protect their lives and property.
INTERCONNECT RADIO TESTING: Test by pushing the
test button on the cover and holding it down for a minimum
of 6 “chirp”. This alarm red LED would light steady. and the
sound will change to steady from “chirp”. And then the
alarm will send radio alarm signal to other radio link
alarms.
TEST THE ALARM WEEKLY TO ENSURE PROPER
OPERATION. Erratic or low sound coming from your alarm
may indicate a defective alarm, and it should be returned
for service.
5. NUISANCE ALARMS
Smoke alarms are designed to minimize nuisance alarms.
Cigarette smoke will not normally set off the alarm, unless
the smoke is blown directly into the alarm.
Combustion particles from cooking may set off the alarm if
the alarm is located close to the cooking area. Large
quantities of combustible particles are generated from
spills or when broiling. Using the fan on a range hood
which vents to the outside (non-recirculating type) will also
help remove these combustible products from the kitchen.
If the alarm does sound, check for fires first. If a fire is
discovered, get out and call the fire department. If no fire is
present, check to see if one of the reasons listed in Section
2 may have caused the alarm.
6. MAINTENANCE
BATTERY REPLACEMENT
To replace the battery, remove the alarm from the mounting
bracket by rotating the alarm counterclockwise.
The Smoke Alarm is powered by a 9V carbon zinc battery
(alkaline and lithium batteries may also be used). A fresh
battery should last for one year under normal operating
conditions. This alarm has a low battery monitor circuit
which will cause the alarm to “chirp” approximately every
30 - 40 seconds for a minimum of seven (7) days,
accompanied by the red LED flash, when the battery gets
low.
Replace the battery when this condition occurs.
8. GOOD SAFETY HABITS
DEVELOP AND PRACTICE A PLAN OF ESCAPE
• Make a floor plan indicating all doors and windows and at
least two (2) escape routes from each room. Second story
windows may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan,
showing everyone what to do in case of fire.
• Determine a place outside your home where you all can
meet if a fire occurs.
• Familiarize everyone with the sound of the smoke alarm
and train them to leave your home when they hear it.
• Practice a fire drill at least every six months. Practice
allows you to test your plan before an emergency. You may
not be able to reach your children. It is important they know
what to do.
CLEANING YOUR ALARM
To clean your alarm, remove it from the mounting bracket
as outlined in the beginning of this section. You can clean
your alarm by using compressed air or your vacuum
cleaner hose to blow or suck air through the openings
around the perimeter of the alarm. The outside of the alarm
can be wiped with a damp cloth.
After cleaning, reinstall your alarm. Test your alarm by
using the test button.
WHAT TO DO WHEN THE ALARM SOUNDS
• Leave immediately by your escape plan. Every second
counts, so don’t waste time getting dressed or picking up
valuables.
• In leaving, don’t open any inside door without first feeling
its surface. If hot, or if you see smoke seeping through
cracks, don’t open that door! Instead, use your alternate exit.
If the inside of the door is cool, place your shoulder against
it, open it slightly and be ready to slam it shut if heat and
smoke rush in.
• Stay close to the floor if the air is smoky. Breathe

• Once outside, go to your selected meeting place and
make sure everyone is there.
• Call the fire department from your neighbor’s home - not
from yours!
• Don’t return to your home until the fire officials say that it
is all right to do so.

9. NFPA REQUIRED PROTECTION
The National Fire Protection Association’s Standard 72
reads as follows:
2-2.1.1.1 Smoke alarms shall be installed outside each
separate sleeping area in the immediate vicinity of the
bedrooms and on each additional story of the family living
unit, including basements and excluding crawl spaces and
unfinished attics. In new construction, a smoke alarm shall
be installed in each sleeping room.
A-2.5.2.1 Smoke Detection - Are More Smoke Detectors
Desirable? The required number of smoke alarms might
not provide reliable early warning protection for those
areas separated by a door from the areas protected by the
required smoke alarms.
For this reason, it is recommended that the householder
consider the use of additional smoke alarms for those
areas for increased protection. The additional areas
include the basement, bedrooms, dining room, furnace
room, utility room, and hallways not protected by the
required smoke alarms. The installation of the smoke
alarms in the kitchen, attic (finished or unfinished), or
garage is normally not recommended, as these locations
occasionally experience conditions that can result in
improper operation.
Since some states do not allow limitations on the
duration of an implied warranty or do not allow the
exclusion or limitation of incidental or consequential
damages, the above limitations or exclusions may not
apply to you.
While this warranty gives you specific legal rights, you
may also have other rights which vary from state to
state.
Also, Convoy Security makes no warranty, express or
implied, written or oral, including that of merchantability
or fitness for any particular purpose, with respect to the
battery.
The above warranty may not be altered except in
writing signed by both parties hereto.
This equipment should be installed in accordance with the
National Fire Protection Association’s Standard 72 (NFPA,
Batterymarch Park, Quincy, MA 02269).
